-The indexmap is a hash table where the iteration order of the
-key-value pairs is independent of the hash values of the keys.  It has
-the usual hash table functionality, it preserves insertion order
-except after removals, and it allows lookup of its elements by either
-hash table key or numerical index.  A corresponding hash set type is
-also provided.
